Research on Pile-Soil Stress Ratio of DJM Pile Composite Foundation

Abstract:

Article Preview

Pile-soil stress ratio is defined as the average stress ratio of the head of pile to the soil around of piles, which is a very important indicator to reflect the level of the together-work of pile and the soil, also a major parameter of calculation of capacity of composite foundation and settlement. How to choose pile-soil stress ratio is still a problem unsolved. Bearing performance of the DJM pile composite foundation is studied by way of field static load tests and pile-soil stress ratio tests. This paper is to analyze the bearing performance of the DJM pile composite foundation in the Yellow River Delta region with the plane strain finite element method and gain the load-sharing ability of soil and regulations of pile-soil stress ratio with the changes of effecting factors.
